Transistor Test
1. Set the function/range switch to the hFE position.
2. Determine whether the transistor is a NPN or PNP and identify the emitter,
base and collector leads. Insert the leads in the proper holes in the hFE socket.
3. The LCD will read approximate hFE values based on the test condition of the
10
µ
A DC base current and Vce of approximately 1.5 V DC.
Continuity Check
1. Set the function/range switch to the OHM / position.
2. Insert the black (negative) test lead into the "COM" jack and the red (positive)
test lead into the V/
Ω
/F/ / jack.
3. Press the / button until OL and appear on the LCD.
4. Touch the test lead tips across the devise under test.
5. If the resistance is less than 30
Ω
the audible signal will sound. If the resistor
is part of the circuit, it is necessary to disconnect one end of the resistor to
avoid the unwanted intererence from the rest of the circuit.
CAUTION: Never measure a device that has voltage on it.
Capacitance Measurement
1. Discharge the capacitor being tested before starting the measurment.
2. Set the function/range switch to the CAP position.
3. Insert the black (negative) test lead into the "COM" jack and the red (positive)
test lead into the V/
Ω
/F/ / jack. NOTE: The multimeter will be in auto-ranging
only.
4. Touch the test lead tips across the devise under test. The red test lead to the
positive and the black test lead to the negative.
5. Read the value and unit shown on the LCD. If OL is displayed, the value of
the capacitor is over the maximum range of the multimeter.
Frequency Measurement
1. Set the function/range switch to the FREQ% position.
2. Insert the black (negative) test lead into the "COM" jack and the red (positive)
test lead into the V/
Ω
/F/ / jack.
3. Press the Hz/% button until the "Hz" appears on the LCD.
4. Touch the test lead tips across the devise under test.
5. Read the value and unit shown on the LCD.
CAUTION: Never input the voltage over 250 V AC/DC.
